I'm just curious on how much faster the ATA Serial hard drives are going to be over IDE hard drive that are starting to come out. The reason I'm asking is because I bought a new Asus P4PE motherboard last month for a machine I'm going to build myself. The only thing is, I bought the cheap one, the P4PE/L. I'm thinking about dumping it on ebay and buying the one with firewire, gig lan, and serial ATA. Just trying to determine if it's worth it.
